Biological Properties
General Functionvacuole inheritance
Specific FunctionMAP4K component of the MAPK pathway required for the mating pheromone response, haploid invasive growth and diploid pseudohyphal development. Links the pheromone response G-protein beta gamma subunits to downstream signaling components. Needed for mating in haploid cells, induction of a mating-specific gene FUS1, induction of mating-specific morphologies, and pheromone-induced proliferation arrest. Required for the regulation of the actin polarization and bud emergence during cell cycle in G1. Involved in the high osmolarity glycerol (HOG) response. Phosphorylates 'Thr-307' and 'Ser-302' or 'Ser-306' of STE11 and 'Ser-357' of MYO3. Phosphorylates histone H2B to form H2BS10ph during meiosis and H(2)O(2)-induced apoptosis. Its interaction with CDC42 is required for both invasive growth and the formation of pseudohyphae. Its interaction with STE4 is required for the pheromone signaling.
